To reproduce:

1. Download attached project "logMessageSafety.zip" and open in Unity
2. Open "scene" scene
3. Select "Repro" gameObject
4. In Inspector window reset "ConstructorBehaviour" script

Expected results: In Console will be printed two errors
Actual results: In Console will be printed two errors and Application.logMessageReceived will be invoked when API calls are not allowed

Notes:
- This issue reproduces on both Windows and OSX
- The error message itself is expected behavior, but Application.logMessageReceived is now being called as a result of the Log call in the Constructor
- A Customer is reporting this, but as a result of " Serialization depth limit 7 exceeded at..." message
